The reaction of `Cl_(2)` gas with cold-dilute and hot-concentrated NaOH in water give sodium salts to two (different) oxoacids of chlorine, P and Q, respectively. The `Cl_(2)` gas reacts with `SO_(2)` gas, in presence of charcoal, to give a product R. R reacts with white phosphours to give a compound S. On hydrolysis. S gives an oxoacid of phosphorus T.
Q. P and Q, respectively, are the sodium salts of
A. Hypochlorous & chloric acids
B. Hypochlorous & chlorous acids
C. Chloric & perchloric acids
D. Chloric & hypochlorous acids
